To all whom it may concern:

Be it known that I, PHILIP W. MOORE', a citizen of the United States, ,residing at Evanston, in thecounty of Cook and State of Illinois, have invented certain new' and My invention relates to a' device'for pre- ',Venting the longitudinal creep `of railway rails, devicespof this character being. cornmonly called rail anchors, rail stays, or anti- Creepers; and the invention has for its object to provide a device of this sort of novel form` and construction and having certain; improved features to be hereinafter described. The invention is illustrated,l in certain typical. embodiments,.in the accompanying drawings, wherein 7 Figure 1 is an elevation of one form of device shown as applied to the rail, the latterv being in'section'; Fig. 2, a plan View of the Vform of device shown v-in Fig. 1; Fig. 3, a

View, in perspective, ofv one of the clamping elements; Figs-4 and 5 are sectional Views taken on, respectively, lines 4/-4 and 5-5 of Fig. 2, looking in the direction of the arrows; Fig. 6 is a plan View 'of a modified form of anchor; Figs. 7, 8 and 9 are sectional views taken on, respectivelyflines 7 -7 8-8 and 9-9 of Fig. 6, looking in the direction of the arrows; Fig.' 10 is a plan view of another. modification; Figs. 11,' 12 and 13 are sectional views taken on, respectively, lines 11-11, 12-12 and 13-13 of Fig. 10, looking in the direction of the arrows; Fbig. 14 is an inverted plan view of one of the clamping elements of the .anchor shown in the preceding four igures; Fig. 15, a fragmentary plan of the complementary element; Fig. 16, a View similar to Fig. 1 illustrating f a further modification ofthe form of anchor shown'in'Fi-gs. 10 to 15 inclusive; Fig. 17 is a plan View of this modification, and Figs. 18 and 19 are sectionalv views taken on lines 18-18 and 19-19, respectively,.of Fig. 17, looking in the direction of the arrows.

Like characters of reference indicate like parts in the several figures ofthe drawings.

In all of the figures, 25 designates a rail! way rail, and 26 one ofthe ties upon which the rail rests. The anchor, in each case, con- .sis'ts of two coengaging clamping elements designated 27 and 28,'one` ofl which, that.

designated 27, is adapted to be held in av stationary position with respect to the road speication of Letters ratent.- Patented Nov. '-7, 1911. vAppnaion med July 17, 1911. serial No. 638,895. l'

bed, for example, to be abutteol against the tie 26, tokwhich end .it is 'provided with one fthe clamping elements 27,128 are shown as formed leach with a jaw and a base member adapted to extend under the bottom of the rail, the base members being formed at their extremities with jaws which lit into the first mentioned jaws of the complementary clamp- 'fing elements... Fig. 3 shows the construction of the lamplng element 27. 30 designates the'base member, 31a jaw formed at one end of the same, and 32 a smaller jaw formed at E the other end. The base member 30 is re cessed at one end, as indicated at 33, and at the otheris formed with the projecting part 34. The complementary free element 28 is formed Withvthe jaw 31J1 which extends over jaw 32 on the element 27, and with the jaw v32a which fits into jaw 31. 'The projecting part. 34a of element 28 overlaps and bears upon the recessed portion 33.0f element 27. The projecting portion 34 overlaps and bears upen the recessed portion 35 of the' base member 3()a of the complementary elel'nent 28.

The above description applies also'to the.

modiiied forms of my invention shown in Figsroltopt) inclusive and Figs. 10 tov 13 inclusive." These three embodiments of the inventinditfer only in the means employed or configuration given tothe complementary clamping elements for the purpose of causing them to grip or clamp the rail. In the form of device shown in Figs. 1- to 5 inclusive'the overlapping portions of the base members at'v opposite ends of the anchor are given awe'dge forma-tion, which produces a stress on vertical lines between the superposed surfaces of therail flange and anchor;

sov

vThat is, the under surface 35 of the base'.

member 30 andthe upper surface 35 of the base member v30EL are inclined downwardly l.toward the tie (Fig. 4), while `the coacting surfaces 36, 36, at the opposite end of the anchor, are given a corresponding inclina? tion in the opposite direction' (Fighe):

lVth this construction the clamping act-ion y of the anchor onthe rail flange is entirely up and down. The anchor exerts no lateral pressure aganist therailn Tn the form of anchor shown in Figs. G to 9 inclusive, the

two pairs of wedge surfaces, here designated :37, 37 u and 38, 38, are inclined not only. on vlines transverse of the anchor, but are also aswell as a vertical component. .In the` given a slope downwardly from the middle of the anchor toward the jaws as shown particularly in Fig. 9. With the device so con-j structed the movement of the element 27`to ward the tie causes a stress between the an chor and the rail flange having a horizontal form of device shown in Figs. l0 to'l5 inelusive the element 27 is formed on the under side at one end with an oblique tongue or rib 39 which enters a correspondingly formed groove Zl0 in the element 28. If desired, t-he same construction might be employed atthe other end of the anchor. Thev stress of the anchor on the rail resulting from this construction is entirely a lateral stress. The jaws are drawn toward each other clamping the rail between them.

It will be possible to simplify all of theA above described embodiments of my inven-VK tion by eliminating the inner pair of jaws, in which case the outer jaws bear directly upon the rail flange. In Figs. 16 to 19 in* elusive I have illustrated this construction as a modilication of the form of anchor shown in Figs. l0 to 15 inclusive. Each of the complementary clamping elements has a single jaw and these jaws, designated 41, 4l, bear directly upon the opposite edges of the rail liange. Obviously the anchors shown in Fi s. l to 15 inclusive might be similarly modified.

The operation of the invention will be clear from the above description. Suffice itto say that when the device is applied to the rail^the clamping element 28 may be driven upon the complementary element 27, which latter is abutted against a tie, until a close clamping iit is obtained between the anchor and the rail. Any tendency of the rail to creep will now be checked by the increased stress between the anchors and the rail which such tendency produces. rlhe construction of t-he cao-engaging clamping elements is'such as to resist the tendency of the vibration of the rail to shake the anchor loose. The area of Contact between the elements is considerable so that one isv given a strong frictional grip on the other. The character of the interlock prevents any rocking motion between theelements. Each of the elements engages with the other element at each end of the device, that is, at each side of the rail. These several features give strength to the anchor as well as holding l claim:
